Arthur is not yet sure that he wants to become a father, but his girlfriend, Lucie, is desperately wants a child. On New Years Eve 1999, Arthur is forced to experience his future and see what the consequences will be like if he does not have children now. He meets his son, Ako who reveals the situation and what he must do. Transported to the year 2070 we expect to find the typical mise-en-scène for a sci-fi film, however, to our great surprise it appears that human life has taken several steps backward and Paris is now completely 'ensablé' - covered sand.
